Richard Osman and Katherine Ryan will be doing battle in the second series of Taskmaster.

This year's contestants have been unveiled, with Jon Richardson, Joe Wilkinson and Doc Brown also taking part.

Greg Davies and Alex Horne are returning to front Taskmaster, which puts comedians through their paces in a number of outrageous challenges. Like the first series, rivalry will be encouraged, dodgy tactics rewarded, and pitiful attempts scoffed at.
